Not the only scientist on a banknote
When Germany still had its own currency, the 10 Mark note had Carl Friedrich Gauss together with his eponymous bell-curve distribution, both on a graph and a formula.
Which reminds me that when I worked in Germany a Japanese colleague from the same lab asked me if I remember the Gauss distribution formula. I told him to look at the 10 Mark note. He did but went to the library to double check. He was surprised the formula was correct.
